SECTION 1: PRODUCT INFORMATION 1.1 Introduction We appreciate your business and your choice of Welker products. The installation, operation, and maintenance liability for this product becomes that of the purchaser at the time of receipt. Reading the applicable Installation, Operation, and Maintenance (IOM) Manual prior to installation and operation of this equipment is required for a full understanding of its application and performance prior to use.* If you have any questions, please call Welker at 1-281-491-2331. *The following procedures have been written for use with standard Welker parts and equipment. Assemblies that have been modified may have additional requirements and specifications that are not listed in this manual. 1.2 Product Description The Welker LE-2SSKO Probe Mounted Liquid Eliminator is designed to remove entrained liquids, condensed hydrocarbons, glycol, and amines from gas samples, ensuring the collection of representative samples and protecting analyzers from damage and contamination. Pipeline product enters the LE-2SSKO through the probe. The gas stream passes through the LE-2SSKO to the sample outlet, but any liquids present are separated from the sample stream by centrifugal flow, a membrane, and a screen and then returned to the pipeline through the stinger. Optional features provide additional protection from entrained liquids. The Welker x-wave Probe Tip and Welker ALS-1 Analyzer Liquid Shutoff are designed with a floating ball that will seal if liquid tries to pass through. The x-wave Probe Tip acts as a first defense against liquids, allowing only gas to enter through the probe of the LE-2SSKO. The ALS-1 acts as a final defense against liquids, shutting off product flow to the analyzer in the presence of liquids. Welker may custom design the LE-2SSKO to suit the particular application and specifications of each customer. 4 IOM-069 MODEL: LE-2SSKO REV: E 13839 West Bellfort Street Sugar Land, TX 77498 welker.com Service Department: 281.491.2331

SECTION 2: INSTALLATION & OPERATION 2.1 Before You Begin After unpacking the unit, check the equipment for compliance and any damage that may have occurred during shipment. Immediately contact a Welker representative if you received damaged equipment. When sealing fittings with PTFE tape, refer to the proper sealing instructions for the brand used. 1. Welker recommends that the unit be installed in the top of the pipe and inserted into the center one-third (1/3) of the pipeline in a location where the product is well-mixed and will yield an accurate and representative sample. 2. The sample probe should be located in the least turbulent area of the flowing stream available (i.e., not in a header or non-flowing area and away from obstructions, elbows, and partially closed valves). 2.2 Installation & Operation The pipeline must be depressurized prior to installing and removing the unit. If the LE-2SSKO is equipped with double block and bleed valves, refer to Addendum A, LE-2SSKO With Double Block and Bleed Valves, for instructions on correctly installing the unit. If the LE-2SSKO is equipped with optional regulator(s) and filter, refer to Addendum C, LE-2SSKO With Regulator(s) and Filter, for instructions on correctly installing the unit. If the LE-2SSKO is equipped with the optional x-wave Probe Tip, the x-wave Probe Tip may seal dry and prevent product from reaching the outlet if the pipeline flow is greater than 400 cc/minute. 1. Ensure that inlet (P 1) valve A and return (P 2) valve B are closed (Figure 1). 2. Ensure that all cap screws on the top cap are tightened (Figure 1). 3. Ensure that the pipeline is depressurized. 4. As necessary, wrap the threads of the threaded pipeline connection with PTFE tape. 7 IOM-069 MODEL: LE-2SSKO REV: E 13839 West Bellfort Street Sugar Land, TX 77498 welker.com Service Department: 281.491.2331
5. Install the LE-2SSKO to the pipeline so that the stinger is downstream of the direction of product flow (Figure 2). As necessary, refer to the flow direction stamped on the top cap to determine correct orientation before installing the LE-2SSKO to the pipeline. Figure 2: Correct LE-2SSKO Installation 6. Using customer-supplied tubing, connect from the product outlet to the customer s downstream instrument(s) (e.g., a regulator assembly connected to an analyzer) (Figure 1). 7. Pressurize the pipeline. 8. Open inlet (P 1) valve A and return (P 2) valve B (Figure 1). Check for leaks at the pipeline connection and repair as necessary. 9. The LE-2SSKO is now operational. 10. If liquids are present at the product outlet, maintenance is required. See Section 3.2, Maintenance, for instructions on performing maintenance on the LE-2SSKO. 11. If the LE-2SSKO is equipped with the optional ALS-1 Analyzer Liquid Shutoff, observe the ball in the ALS-1. If the ball rises and shuts off the ALS-1, liquid has entered the system and maintenance is required. Refer to Addendum B, LE-2SSKO With ALS-1, for instructions on maintaining the LE-2SSKO with ALS-1. 12. If the LE-2SSKO is equipped with the optional x-wave Probe Tip, visually verify that the gas stream can reach the product outlet. If product is not observed at the outlet, the force of the pipeline flow may have caused the ball to lock, requiring maintenance on the x-wave Probe Tip. Refer to Addendum D, x-wave Probe Tip, for instructions on maintaining the x-wave Probe Tip. 8 IOM-069 MODEL: LE-2SSKO REV: E 13839 West Bellfort Street Sugar Land, TX 77498 welker.com Service Department: 281.491.2331
SECTION 3: MAINTENANCE 3.1 Before You Begin 1. Welker recommends that the unit have standard maintenance every six (6) months under normal operating conditions and any time liquid is present in the copolymer flat membrane or at the product outlet. In cases of severe service, dirty conditions, excessive usage, or other unique applications that may lead to excess wear on the unit, a more frequent maintenance schedule may be appropriate. 2. Prior to maintenance or disassembly of the unit, it is advisable to have a repair kit available for repairs of the system in case of unexpected wear or faulty seals. New seals supplied in spare parts kits should be lightly lubricated before being installed. This eases the installation of the seals and reduces the risk of damage when positioning them on parts. Welker recommends non-hydrocarbon-based lubricants, such as Krytox, for use with all sample cylinder seals and silicone-based lubricants, such as Molykote 111, for use with seals not exposed to the sample product. Wipe excess lubricant from the seals, as it may adversely affect analytical instrument results. After the seals are installed, the outer diameter of shafts and inner diameter of cylinders may be lubricated to allow smooth transition of parts. 3. All maintenance and cleaning of the unit should be performed on a smooth, clean surface. 3.2 Maintenance If maintenance on the valves, probe, stinger, or optional x-wave Probe Tip is required, the LE-2SSKO must be isolated from pipeline pressure and removed from the pipeline before maintenance can be safely performed. Prior to performing maintenance, the LE-2SSKO must be isolated from pipeline pressure. However, the LE-2SSKO does NOT need to be removed from the pipeline to perform standard maintenance. If the LE-2SSKO is equipped with double block and bleed valves, refer to Addendum A, LE-2SSKO With Double Block and Bleed Valves, for instructions on removing and performing maintenance on the unit. If the LE-2SSKO is equipped with the ALS-1 Analyzer Liquid Shutoff, refer to Addendum B, LE-2SSKO With ALS-1, for instructions on removing and performing maintenance on the unit. If the LE-2SSKO is equipped with optional regulator(s) and filter, refer to Addendum C, LE-2SSKO With Regulator(s) and Filter, for instructions on performing maintenance on the unit. 9 IOM-069 MODEL: LE-2SSKO REV: E 13839 West Bellfort Street Sugar Land, TX 77498 welker.com Service Department: 281.491.2331

ADDENDUM D: x-wave PROBE TIP D1.1 Product Description The Welker x-wave Probe Tip is designed to prevent failure of the LE-2SSKO caused by slugs of liquid in the pipeline and shortterm flooding by reducing the volume of liquid that enters the probe. When the liquid level in the pipeline rises, the liquid pushes the ball inside the x-wave Probe Tip up, creating a seal and preventing the LE-2SSKO from being flooded by the liquid. When the liquid level falls, the stinger relieves pressure in the LE- 2SSKO, breaking the seal of the ball and allowing product flow through the probe. The x-wave Probe Tip will not prevent failure of the LE-2SSKO caused by long-term flooding. 1.2 Specifications The specifications listed in this section are generalized for this equipment. Welker can modify the equipment according to your company's needs. However, please note that the specifications may vary depending on the customization of your product.
